What should i be carefull about when moving through firmware versions?
For ex: from 5.1.2 Moto to 4.4.4 GPE, or 4.4.4 Moto to 4.4.4 GPE.
As far as i know, when switching from LP to KK you cant downgrade BL (flash motoboot.img), in my case i have the lastest one already.
And also i know that Moto and GPE have different partition tables, so i dont know if i should flash gpt.bin or not in this case. Furthermore id like to know if gpt.bin should be flashed while downgrading from 5.1.2 Moto to 4.4.4 Moto.
All information is apreciated, i really want to learn this. Greetings!
Do not touch the Bootloader unless you have a really good reason.
You can easily change between ROMs using Custom Recovery. You do not need to think about partition tables, only how /data (userdata) is formmated. GPE uses EXT4, all other Stock Motorola Firmware uses F2FS. Even then, GPE can be used with F2FS if you flash a different Kernel. For example, you can Boot GPE 4.4.4 with a Stock Motorola non-GPE 4.4.4 Kernel.

Okay so my moto g is on lolipop gpe converted, but i want to go back stock. i know how to flash it and stuff but is there a chance i can brick it due to bootloader differences or anything? like how do i go about this do i need 4.4.4 or is 4.4.2 ok? thanks. *URGENT*
To be safe, flash a 4.4.4 ROM but don't flash motoboot.img even if you don't have the 41.18 bootloader.
I was able to flash my xt1032 with the 41.18 bootloader back to stock Telus 4.4.4. I was even able to flash stock US Retail 4.4.4. I never tried 4.4.2 and I never flashed motoboot.img.

how do i know if its 4.4.4 or 4.4.2??
You'll have to look at the Moto g firmware names. Sometimes, you have to guess. It;s important because you want to ensure that the modem in your phone supports the ROM and carrier.
Do you have the xt1032 (i.e. falcon)?

yeah mate thats the one
What bootloader is on your phone? If you have the 41.18, you'll experience the ripple effect on your phone until you lock/unlock your phone using the lockscreen.
Hi,
My search skills are very bad so pardon me if this has been asked too many times.
I've read somewhere that downgrading is possible by manual method without flashing the gpt and motoboot file.
Once downgrade is done. is it possible to install a custom kitkat rom afterwards?
You should be fine. Flashing gpt.bin file is necessary when coming from a GPE to non-GPE ROM. GPE and non-GPE do not use the same file format for user data.

I have a moto g global version xt1032.
Thanks. I actually installed lost101's optimized 5.02 which i did not think was a gpe version. however, I downgraded to 4.4.4 using a script to 4.4.4 gpe. I am getting ota for 5.0.1. If I do want to update to it sometime, will it work?
If you are on stock 4.4.4 with stock recovery and unrooted, OTA should work.
Hi, i've been reading a lot of posts explaining how to do "GPE LP to KK", and other things, but i want to know if i can flash the BR 5.0.2 firmware image directly above my 5.0.1 GPE without any problems. Thanks in advance
If you manually flash the stock BR 5.02 to each partition using fastboot commands, you should be fine. Every file will flash except for the motoboot file. I say this because I was able to flash stock Telus 4.4.4 on an xt1032 that I converted to the GPE edition.
So doesn't matter if motoboot refuse to flash, because GPE and Stock LP have the same included, right?
For me, stock 4.4.4 and stock 5.02 both worked on my xt1032 with bootloader 41.18.
Even if you tried to flash an older bootloader, it would fail the validation check.
Ok finally i managed to downgrade to EU retail 4.4.4 and then OTA to 5.0.2. All the process was great. Thank you for your help [emoji4]
I have converted my moto g to gpe. I've literally love the speed of 5.1 and can't go back.. Since all ROMs for 5.1 are buggy(at least for me) I've decided to try official ota gpe. I know I should revert back to stock kitkat gpe which is easy but I'm afraid the ota update for lollipop might brick my device since it's not gpe and that it already has lollipop bootloader from dual sim moto g. Is it possible to do this without running into fatal issues ?
It's not worth the risk. Moto G is getting old now, if you brick; there might not be a firmware image to get you out of it. I will create a flashable zip when a TWRP backup is available.

YOu can flash the 4.4.4 firmware and OTA it to 5.0.1
but if u flash 4.42 firmware,ur phone will be hard bricked
So whats u have to do is
flash 4.4.4---->flash 5.0.1---->flash 5.1
voila
I have a XT1032. In the past it ran Motorola (not GPE or anything) Kitkat 4.4.2. Three months ago I upgraded it to GPE 5.0.1, because of my stupidity for not realizing what "GPE" meant. I hate this GPE and have already done with it. Could you guys, please, show me a way to go back to Motorola firmware Kitkat 4.4.2. I don't want anything relating to GPE anymore. :crying::crying::crying:
My XT1032 is en-us version, FYI.
Download the stock 4.4.4 ROM for your phone from here: http://www.filefactory.com/folder/c6cdedc45a775d27/?sort=filename&order=ASC&show=100&page=1
Flash it manually using fastboot commands. Do no flash anything below 4.4.4 as doing so may brick your phone.

Thank you. Instead of downgrading, can I upgrade GPE 5.0.1 to Motorola 5.0.2, then wait for Motorola 5.1 OTA update? Is there any risk to switch between GPE and non-GPE (Motorola)?
The partition layouts are slightly different and I believe the data partition on gpe (ext4) and stock (f2fs) are not the same.

audit13, I really don't understand all the commands I need to type when using mfastboot. When upgrading my phone to GPE, I followed this post (http://forum.xda-developers.com/moto-g/general/gpe-ota-lrx21z-5-0-1-xt1033-xt1032-t2969847). Is there any difference? Could you show me some links to learn about how to use those commands? I don't know what I should type, what I should do step-by-step. Thank you.
